去年は12月1日に開始し、7記事しか書けずにおわったアドカレ。
半年くらい、この時を待っていました。
過去Qiitaアカウントを一新して、今年はZennで臨もうと思っていましたが、

Qiitaでの記事投稿でないと完走賞の対象外になってしまう旨、見知らぬどなたかが案じてくださり、問い合わせまでしていただいたらしく、Qiitaの運営さんから確認メールを受け取った次第です。

御心遣い、誠にありがとうございました。

お知らせいただかなければ、Qiitanを貰えずに、この想い、無念に断ち切られてしまうところでした。

((┐_ _)┐

QiitaのSEOが強すぎて、恐れ多く別舞台を選びたい所存でしたが、心機一転、25記事恥なく完走できるよう挑みます。

Qiitan、待っててな。
